Sound structures, expertly engineered.
Grand Innovations provides a full range of construction services, from structural modifications and new-build annexes to brickwork, stonework, groundworks and drainage. We work on both modern and period properties, applying traditional craftsmanship alongside contemporary building techniques to deliver results that are structurally sound, visually exceptional and fully compliant.
Our construction team handles everything from underpinning and foundation work through to steel beam installation, load-bearing wall removal and complete structural reconfigurations. Whether you need a new garden room, a detached home office, or the structural shell to support a major extension, we deliver every project with precision and transparency.
Every job is designed by a chartered structural engineer, submitted to building control for approval, and billed weekly against completed, signed-off work — so you always know exactly where your project and your money stand.

Our capabilities.
From the groundworks up to the steel that holds it all together — the full structural skill set under one roof, delivered by our own directly employed team.
Structural Modifications
Underpinning, foundations, chimney breast removal and full structural reconfigurations — every job designed by a chartered engineer and signed off by building control.
Annexes & Garden Rooms
Detached home offices, garden studios and self-contained annexes built from the ground up — insulated, serviced and finished to live in all year round.
Brickwork & Stonework
New-build walls, garden and retaining walls, decorative features, repointing and chimney repair — with brick and mortar carefully matched on period properties.
Groundworks & Drainage
Excavation, foundation preparation, drainage runs, soakaways and connections to mains services — the solid, unseen groundwork every sound build depends on.
Steel Beam Installation
SpecialistEngineered RSJs and goal-post frames to open up rooms and carry new loads, with temporary propping, padstones and fire protection all handled.
Load-Bearing Wall Removal
Knock-throughs done properly — structural calculations, supporting steels and a flush, plastered finish that looks like the wall was never there.
Structural expertise.
Major changes to a home stand or fall on what happens behind the plaster. As a full building company, we take on the structural work most firms have to subcontract — underpinning weak foundations, installing engineered steels, and removing load-bearing walls to transform how a property works.
Every structural element is designed by a chartered engineer, propped and installed safely, then inspected and signed off by building control. The result is a home that's reconfigured, extended or strengthened with complete confidence — and a paper trail that protects its value for years to come.
